WINDOW Filed Jan. 16, 1940 3 Sheets-Sheet 5 Patented Aug. 17, 1943UNITED STATES PATENT OFFICE wmnow Edwin G. Bunjes, Lcs Angeles, Calif.Application January 16, 1940, Serial No. 314,063 7 '2 Claims. (Cl.268-21) This invention relates to windows, and. more particularlyto'windows comprising a plurality of with the screens if they openoutwardly. One

of the objects of the present invention is to overcome thesedifficulties.

Heret'ofore, French windows have been-the only'type that could easily becleaned on both sides by a person remaining entirely on the inside ofthe room, an advantage that has been offset by the above mentionedcomplications involving curtains, drapes and screens. An additionalobject of the present invention is to provide a window that may be aseasily cleaned as theFrench type without any of the disadvantagesassociated therewith. 1

Other objects of the invention herein described, are the attainment of adecorative effect simulating that of Venetian blinds; the exclusion ofrain and outside air; the provision of means for opening certain of thepanes for ventilation or other purposes while leaving the remainder ofthe panes in closed position, and of means for opening and closing allof the panes by a single control. Still other objects will appear as thespecification proceeds.

In each of the three species of my invention coveredby thisspecification, the window comprises a series of panes Al, A2, A3, A4,and A5, substantially as shown in Fig. l, the exact number of panesbeing a matter of choice or design. Each of these panes is supported bya holder 13. or B followed by other indicia, as indicated in Figs. 1, 2,6, '7, 8 and 14. By means of shafts C that are integral with theholders, these panes I are pivoted in the frame D, in a manner to bemore fully described.

When ventilation only is required, it may frequently not be desirable toopen all the panes, and for this reason provisions have been madewhereby the upper and lower panes may be opened independently of therest; and another control is provided for opening these intermediatepanes when the upper and lower ones are already open, or for opening orclosing the entire group. One form of this operating mechanism comprisesa series of arms El to E5, Fig. 3, connected respectively to shafts CIto C5. The upper and lower arms El and E5 are connected at the outerends to rod F, and the on, shaft H, journaled in plates Ja and Jb ofbracket J, attached to the under side of sill K by screws L. Asindicated in Fig. 4, arm EG is freely rotatable on shaft H, while arm EFis at- A bevel gear tached to the shaft by pin MI.

NF is attached to shaft H by means of pin M2, and the hub O of this gearabuts against piece lb of the bracket. Bevel gear PF meshes with gearNF, and is attached by means of pin M3 in its hub 02 to shaft QF,carrying crank wheel RF on its outer end. Shaft QF is journaled in pieceJc of bracket J, and is additionally supported by escutcheon T2,fastened to the undersill S, through which said shaft passes.Longitudinal movement of shaft QF is prevented by hub 02 and collar Ul.

Through the instrumentality of the mechanism just described, it will beobvious that the upper and lower panes may be opened and closed by theoperation of crank wheel RF. The rotation of this crank to the rightcauses gear PF to turn in the direction indicated by the arrow thereon,causing gear NF, Fig. 4, to turn toward the operator, thus raising theoperating arm EF and, through link F, arms El and E5, which rotateshafts Cl and C5 in the direction required to open panes Al and A5.These sections of the window may, of course, be closed by turning crankRF to the left.

Gear N, which freely rotates on shaft H, functions to open panes A2, A3and A4 if the upper and lower panes are already open, or to open andclose them all. This gear is provided with an arcuate opening V, Figs. 3and 5, extending from about 90 to 180 around the center. Pins WF and WG,attached respectively to operating arms EF and EG, both protrude intoslot V, but they are positioned on these arms at different radialdistances from the centers so that they may pass in slot V, which iswide enough to accerrr odate them both. As shown in Fig, 4, arms and EGare located on opposite sides of gear N, with washers X intervening.Gear N mwhes w th gear P, attached to shaft Q by means of pin M4 in hubO. The other end of shaft Q carries crank wheel R. This shaft isjournaled in front piece Jc of bracket J, and is given additionalsupport by escutcheon T, attached to under-sill S. Longitud nal movementof this shaft is prevented by its hub O and collar U3. Operating arm EGrotates arms C2, C3 and C4, through the linkage system previously explaned.

Assuming that gear N is in the position shown in F g. 5. it will beobvious that arm EF, in opening the up er and lower panes. could havebeen turned to the pos tion indicated by means of the mechanismpreviously expla ned without imparting any motion to gear N, as pin WF.on arm had free space in sl t V in which to move. If crank R is nowturned to the right, as indicated by the arrow, the associated gearswill also turn in the directions indicated by the respective arrows.This movement of gear N w ll cause the lower edge Y of slot V to engagepin WG, thus raising arm EG and opening panes A2, A3 and A4, through therespectively associated arms C2, C3 and C4 and the interconnecting linkG.

If it is now desired to close all the w ndows, crank R is turned in theopposite direction. As the upper edge Z of slot V will nowbe aconsiderable distance beyond pins WF and WG, crank R with the connectedgears P and N must turn a considerable distance before the lost motionis taken up and pins WF and WG engaged. Edge Z will then press on thesepins and move both arms EF and EG- to their downward positions, closingall the panes. At the end of this operation, pin WG will be in theposition shown in Fig. 5, but pin WF will have been turned to a positionbeside pin WG, and edge Z of slot V will be in engagement with bothpins.

Should it now be desired to open the ventilating panes, the rotation ofcrank RF will cause the connected parts to move arm EF upward. Inasmuchas pin WF will be in contact with upper edge Z of slot V, this upwardmovement of arm EF will cause gear N to turn, but no motion will beimparted to arm EG because the lower edge Y of the arcuate slot will bea considerable distance behind pin WG and will therefore not engage it.

If the mechanism was last used to close all the windows, and it is nextdesired to open them all, edge Z of the slot will be found in contactwith pins or lugs WF and WG, and crank R must therefore be turned untiledge Y moves around to the position of pins EF and WG before theoperating arms EF and EG will start to move and to open the panes,

If the upper and lower panes are open and the remainder closed, theoperating arms will be in the positions shown in Fig. 5, and theposition of gear N will be as indicated or somewhere between thisposition and one in which edge Z would be in contact with pin WF. In anyof these possible positions of gear N, it is obvious that the closing ofthe ventilating panes and the necessary downward movement of operatingarm EF and the attached pin WF, will not cause any movement of gear N,as pin WF will have free space within the slot in which to move.

The species of operating mechanism shown in Figs. 9 and 10 may at firstappear radically different from the species hereinbefore explained, butthe following explanation will disclose that it embodies the sameinvention, as broadly defined in the appended claims.

Crank RF, Fig. 10, for operating the ventilating vanes, is attached toshaft QF journaled in sides Jo and Jg of the channel shaped member J,and constrained against longitudinal movement by collars UI and U5. Thisshaft bears pinion PF, meshing with rack NF, an integral part of rod F,mounted for longitudinal movement in horizontal pieces Jd and Je,supported in member J. Rod F bears another rack portion 8, meshing withpinion E5 carried on shaft C5, which operates the lower pane in themanner previously described and therefore not repeated here. The upperportion of rod F has another rack section like rack portion 8, foroperating the upper pane through another pinion and shaft, but as theseparts are duplicates of those just referred to, they are not shown inthe drawings.

Crank R is attached to shaft Q, carrying pinion P, and prevented frommoving longitudinally by collars U3 and U4. Pinion P meshes with rackportion 6 on rod N, which serves the same purpose as gear N in thespecies previously explained. Two spaced lugs, Y and Z, are mounted onone side of rod N. Tappets WF and WG are mounted respectively on rods Fand G in such a manner that they enter the paths of lugs Y and Z so asto be engaged thereby upon longitudinal movement of rod N, which isslidably supported in pieces Jd and Je. Tappets WF and WG are adapted topass each other without interference, as will be apparent from Fig. 10.Rod G is attached to rod Ga by an intermediate member Gb, jointed bybolts, screws or other appropriate means so that rods Ga and G moverectilinearly as a unit in the supports J 11 and Je. Rod Ga has a rackportion 1, meshing with pinion E4 on shaft C4, and other identical rackportions, not

shown in the drawings, are provided for other pinions that are similarlyconnected to the shafts that operate the other intermediate panes.

If the rods are in the position illustrated in the drawings, the upperand lower panes will be open and the intermediate panes closed. If crankR is now turned so that shaft "Q rotates in the direction indicated bythe arrow around it, rod N will be moved upward through the action ofpinion P on rack section 6, and lug Y, shown in engagement with tappetWG. will raise this tappet and thus move rods G and Ga. upward, openingthe center group of panes through the instrumentalities of the variousassociated parts already described.

After the operation just mentioned, all the windows will be open and lugY will be in contact with both tappets WF and WG. If it is now desiredto close all the panes, crank R. is turned in the opposite direction,but no movement will be imparted to rods F and the integral GGa assemblyuntil the lost motion is taken up between lug Z and the tappets. Afterthey have been engaged, however, the further downward movement of rod Nwill cause the tappets to push their associated rods downward, thusclosing the panes.

If the ventilating panes are open and the remainder closed, theoperating rods will, of course, be in the position shown in thedrawings. It will be obvious that the downward motion of rod F to closethe ventilators will not cause any movement of rod N, because tappet WFwill move through the open space between lugs Z and Y.

If the last operation of the mechanism was to close all the windows,tappet WG will be in the position shown in,the drawings, but tappet WFwill be beside it, with lug Z in engagement with them both. Should itnow be desired to open all the panes, the rotation of crank R. willcause rod N to move up until lug Y contacts tappets WF and WG withoutimparting any motion to the rest of the mechanism, but after the tappetshave been engaged, the further upward movement of rod N will raise bothtappets and the rods to which they are attached, thus opening all thewindows through the operation of the various previously describedinterconnected parts.

The preferred form of my operating mechanism is that shown in Figs. 12,13 and 14. In this embodiment, which resembles the species firstdescribed, bevel gear NF and operating arm' EFI, attached so that bothturn as an integral unit, are mounted on shaft CI of lower pane A5.Bevel gear PF, Figs. 12 and 14, meshes with gear NF, and is attached toshaft QF journaled in pieces Jc2 and Jg2 of bracket J, the latter piecebeing adapted to receive the reduced end 9 of shaft QF, which passesthrough the trim, or window mold, piece ll) of frame D to carry crankwheel RF on its outer end.

Bevel gear N, Figs. 12 and 13, is free to rotate on shaft C3 of themiddle pane holder, but it will be understood that shafts C2 or C4 wouldsuffice as well. Operating arm EF3 is also free to rotate on this shaft.Rod F is attached to operatin arms EF and EF3, as well as to arm EFI,this last arm EF and connection not being shown in Fig. 11 because thispart of the construction is identical to that pictured in Fig. 3.Operating arm EG is attached to shaft C3 by pin M5. Gear N has anarcuate slot V like that in the corresponding gear in Figs. 3, 4 and 5,and into this slot protrude the tappet pins WF and WG attachedrespectively to operating arms EF3 and EG. Link or rod G is attached tooperating arm EG, which operates the intermediate panes in identicallythe same way as does rod G in the embodiment first described. The onlydifference in the operation of this third species of my operatingmechanism and that of the first species, lies in the fact that theindependent operation of the ventilating panes is controlled from adiflferent shaft than that which moves them in conjunction with theother, or intermediate, panes;

If the bracket J of Figs. 9 and 10 is of metal, the shafts c of the paneholders may be journaled directly in the bracket on the right side ofthe window. On the left side, independent bearings may be provided, or astrip of metal similar to II in Fig. 12 may be used to furnish bearingsfor all the shafts. In the first and third species, this last bearingmeans is preferred, because the bearing holes may be drilled in two suchstrips simultaneously from a template, and these may be mounted on theouter surfaces of the stiles of the window frame, as indicated in Figs.12, 13 and 14, in which bearing strip II is shown attached by means ofscrews It to stile l2. The stiles are drilled to provide holes l4, Figs.13 and 14, for each of the pane holder shafts, and each hole has acounter-sunk or enlarged portion l5 to receive the hub l6 of theassociated pane holder, into which hub the shaft is rigidly attached bypin I! or other appropriate means.

The brackets J, Figs. 12, 13 and 14, are attached to the stile by screwsl8.

Each side of the pane holders B is U-shaped or channeled, as indicatedin Figs. 2, 8, 13 and 15, and in the form shown in Figs. 2 and 6, itconsists of three integral sides |8, l9 and 20 into which the plate ofglass may be slipped and cemented. .When the holders are four-sided, asin Figs. 7 and 8, it is necessary that the fourth side 2| be made in aseparate piece so that the glass may be slipped into the three-sidedportion l8, l9 and 20 and then the fourth side 2| slipped over theremaining edge of the pane. This fourth side can be cemented to theglass, and then, if desired, it may be soldered, welded or otherwiseattached to sides I8 and 20. It is, of course, immaterial which threesides are made in one piece, and which becomes the fourth side.

When the holders are three-sided, they articulate as shown in Fig. 2,the upper unprotected edge 23 of each plate of glass fitting againstportion 22 of the lower edge of side |9 of the adjoining pane-holderabove. This construction prevents wind or rain from passing the joint.

When the holders are four-sided, the upper side 2| of the frame fitsagainst the abutment 22 on side IQ of the holder next above.

If it is desired to provide a tighter fitting joint between adjacentpane holders, this may be accomplished by attaching a piece of springmetal to portion 22 of the lower side of the holder. This spring metalstrip should have a cross section similar to that shown in Fig. 15, inwhich pane AI is shown partly opened, with strip 24 out of contact withedge 2| of the next lower pane holder. When the pane is closed, thespring strip presses tightly against edge 2| of the holder below,causing it to take substantially the shape indi cated on holder 3:12.

It is necessary that stops or a beading be provided to liimt the angularmovement of the pane holders and to close the space that would otherwiseexist between their outer edges and the adjoining stiles. The stops maybe made of wood, rubber, or other material, such as a plastic. Moldedrubber is perhaps the best. A stop 25, Fig. 2, is provided for the lowerpart of each pane holder, and another stop 21 for the upper part. Thesestops 25 and 21 have formed portions 26 and 28 respectively to fitaround the hub l6. Beading or stops of the type just described is usedon both the right and left stiles of the window, with a pair of stopsfor each end of each pane holder. A strip of heading or moulding 29 isattached to the upper portion of the window frame for the edge 23 ofpane Al to fit against in the closed position, and another similar strip30 is provided at the bottom to close the space that would otherwiseexist between sill K and the lower side l9 of pane holder B5.
